The Samsung Galaxy S2 has finally made its way to the US, but you might want to hold off for a while longer, if you can. A leaked slide has revealed details about the Samsung Galaxy S3, and it’s going to be one seriously kick-butt Android phone.

If the slide is to be believed, the Galaxy S3 starts things off with a Samsung Exynos 4212 processor clocked at 1.8GHz. It’s an ARM Cortex A9 chip built using Samsung’s 32nm High-K metal gate process. These new chips offer a 25% performance boost over the last-gen Exynos while simultaneously providing a 30% reduction in power consumption. Samsung also underscores the 4212’s graphical prowess, saying that it’s 50% more powerful than the previous GPU.

Up front, the S3 features a 4.6-inch SuperAMOLED Plus display — likely featuring the same 720×1280 resolution as the Nexus Prime which is expected to be unveiled in the very near future by Samsung and Google. Around back you’ll find a 12 megapixel camera with a 1/2.3″ sensor which should help reduce noise on the pics we take with this high-resolution shooter.

Last but not least, the slide reveals that the Galaxy S3 will feature 2GB of RAM. Couple with the 1.8GHz dual-core Exynos, this memory boost should give the phone plenty of staying power. With Ice Cream Sandwich on the way and more power-hungry apps and games hitting the Android Market, the extra gig could come in handy as developers test the limits of current-gen Android devices

You may also have noticed a change in the Galaxy S3 design. Unlike its predecessors, there’s no solitary button centered at the bottom of the phone’s face. That’s at least partly a move to avoid another legal battle with Apple over Samsung’s Android flagship, but it’s also the result of Ice Cream Sandwich’s integration of Honeycomb tablet controls — those sure look like the same software navigation options I’ve got on the bottom of my Galaxy Tab 10.1.

It might take some time, but we’re looking forward seeing how this one pans out.
